Abstract

A method of communicating data by a user equipment in a wireless communication system, the method includes configuring plural frequency blocks divided from a system bandwidth; receiving scheduling information including a frequency block indicator and resource allocation information for data; and performing a procedure for receiving or transmitting the data via a first frequency block indicated by the frequency block indicator among the plural frequency blocks.

 a receiver; and 
 a processor configured to:
 control the receiver to receive downlink scheduling information including a frequency block indicator and resource allocation information, and 
 perform a procedure for receiving the downlink data via a time-frequency region indicated by the resource allocation information within a first frequency block indicated by the frequency block indicator among configured plural frequency blocks, 
 wherein each of the configured plural frequency blocks is a subset of a system bandwidth. 
 
 
     
     
       12. The user equipment of  claim 11 , wherein the downlink scheduling information is received via a second frequency block different from the first frequency block among the plural frequency blocks. 
     
     
       13. The user equipment of  claim 11 , wherein the downlink data includes one or more transport blocks. 
     
     
       14. The user equipment of  claim 11 , wherein the downlink scheduling information further includes modulation-related information and hybrid automatic repeat request (HARQ)-related information. 
     
     
       15. The user equipment of  claim 11 , wherein the frequency block indicator includes N−1 bits, and each of the N−1 bits represent a boundary between two neighboring frequency blocks in the plural frequency blocks, where N is a number of the plural frequency blocks. 
     
     
       16. A base station for use in a wireless communication system, the base station comprising:
